Thanks guys. Is overkill a member on here or can I get a website/ number? Like I said. Just mild PCM stuff. Nothing special I wanna keep this as stock as possible no cel or other random crap going wrong. but could really benefit from a descent PCM or even canned tune.

Ok. I found him. Overkill Motorsport in Toronto?


seems like a good price for a PCM @ $119. Is there a way to get ahold of him on here or a phone number? I didn't see one on the site

Also. What do you guys think. Des cool. Or flush it for green it has dex in here now and doubt it's ever been serviced. 130k miles

AMSOIL - AMSOIL Dominator® Coolant Boost (RDCB)




Next week I'll have the trans pan dropped, out with the coolant, and In with the Intense shift kit ( also just ordered ) Dex VI, and new filters and seals.. And that will complete the engine mods for the car.. No sense in making it fast, its not meant to be, and will just take away reliability in the long run.. And the fact I have a 06 PCM, Im not realling interested in the swap , for some changed shiftpoints, a new base fuel MAP and some added timing, along with a few dtc deletes...

My SRT was fast, so I got that outta my system lol, Hopefully this one stays rust free , and will let me work on exterior mods and Audio
